IRRIGATION SYSTEM.

Specification of Letters Patent.

Patented Nov. 4, 191 3.

Application filed July 19, 1 912. Serial No. 710,482.

To all whom it may concerni- Be it known that LWVILLLAM G. liLoss, :i citizen of the United lStates,I residing in thecity and county of Los Angeles, State of California, have invented a new and useful Irrigation System, of which the following is a specification.

An object of this invention is to provide a durable, simply Constructed irrigation tem, and one tlijt can be relied upon to thoroughly meisten the soil withoutI intertering with the tilling'thereof.

A further object of the invention is to provide for irrigating groundV having an uneven surface, or having a general slope.

Further objects and advantagesmay hereinafter appear.

The invention consists in the various parts, combinations of parts, and details of construction hereinafter described in connection `with the accompanying drawings, and then denitely pointed out in thefelaim.

Referring to the accompanying drawings, which illustrate 'the invention, Figure 1 is a vertical sect-ion of this irrigation system, the line of section passing through Fig. 2 on line @1l-wml thereof, illustrating the subterranean floor and soil-supporting structure mounted on said floor; Fig. 2 is a plan view of a `portion of Fig. 1; Fig. 3 is a' longitudinal section of two of the tile to illustrate the manner ot joining said tile;` Fig. l is a transverse section on line ait-x* of Fig. 3; Fig. 5 is a vertical section of one of the gates on line :1f-m5 of Fig. 1.

Referring in detail to the drawings, a subterranean reservoir-is provided, the same consisting of a liquid-tight floor 2 and inelosing walls 3, the top of said walls 3 being buried far enough below the surface of the soil fl to be beneath the reach of agricultural implements. pon the Hoor of said reservoir is laid a .lower layer of tile 5 in rowsI which are spaced apart from each other as shown in section in Fig. 1. rhe spaces between said lower rows of tile are bridged by rows of upper tile 6, all ot said tile desirably being in the torni of inverted troughs. In irrigation, the water levelv is maintained a little above the tops (or rather, inverted bottoms) of the lowerl layer of tile. The lower tile are loosely seated upon the floor, and the upper tile being loosely seated upon the lower tile, the water readily percolates between and within the tile and is absorbed by the soil a; The two layers in the form of inverted troughs and of tile form a sort of false bottom over the main floor or bottom 9. to provide a chainber for the water between the soil and the main bottom or floor 2. Buter results are secured when -the tile ot the upper layer are spaced slightly apart, this arrangement permitting an additional supply of the water to rise under the tile up to a level above the earth in the spaccsbetween the tile and to be held in the reservoirs thus Jformed until absorbed into the earth. A lower floor 7 is also providedsaid iioor being inclosed by wall. Tile like the tile 5 and G already referred to, may be laidupon .said lower iior, or overlapping rows of brick 9 may. be placed thereon, said brick being supported by piers 10;

One or more openings 11 are provided through wall 3 to permit the water to escape from the upper reservoir to the lower reservoir and rise to a level somewhat above the 'tops of the upper layer of brick 9 so as to be absorbed by the soil e. The flow ot water through said opening or passage 11 is preterably controlled by a gate 13 working in an upright guide 14- provided with an opening 15 which registers with the passage 11 through wall 3. Small stones 11 may be placed opposite the inlet end o't passage 11 to keep the soil from obstructing said passage. Or, if desired, the tile may be so arranged that their open ends will come opposite to one or more of said passages 11. One oi the brick 9 may be leaned up as shown to keep the outlet end ol? said passage trom being obstructed. rlhe tile will probably be foundmore satisfactory in practical use, but the brick-work is shown to illustrate how the system may be constructed when the tile are not readily obtainable. In both `terms of the invention the joints of the irick or of the tile are made to overlap so as to keep the soil trom sitting down. into the reservoir. 1`hejoints 16 of tho tile 5 are illustrated in Figs. 3

and 4. The upper tile 6 are provided with like joints.

Asshown in Figs. 1 and 2 water is snippliedfrom a conduit 17 which discharges into a pit 18 formed by digging away the soil down to the supporting structure formed by the tile 5 and 6. Two of the lower tile are desirably spaced apart as shown at 19 so as to allow the water free access into the open ends thereof.

are

within the scope of the appended claim, may

be. made without departing of the invention.V

I claim: In an irrigation system, a subterranean from the spirit floor, a soil-supporting structure resting upon said floor to form a 4water chamber and separate the earth from said floor over a relatively large continuous area thereof, a subterranean wall inclosing saidA floor afnl other subterranean floor at a lower level than the first named floor, a structure to form a water chamber above said lower floor, a subterranean wall yinclosing said lower ioor on all sides, a portion of said walls'bei-ng in common, and a water gate to control the flow/of water from the upper chamber to the lower chamber, said'walls, beingdispos'edk at asuflicient distance below the surface of the ground to provide for the cultivation by' tract-ion propelled implements of a field having pronounced variations of surface level and embracing a series of said reservoirs. y l ff In testimony whereof- I have hereunto signed my name in the presence of two subscribing witnesses lat Los Angeles, in the county of Los Angeles and .State of Cali fornia, this 11th day of July 1912v WILLIAM G. BLoss, JESSE W. WHANN.
